And of course Charlie Bucket — who in this version is a black boy, and is accompanied by his two doting parents.

All the others are white?

Yes. So Charlie ends up in the Easter Room, where there are life-size candy molds of creatures, and one of these life-size molds is shaped like a chocolate boy. Charlie is fascinated by this. Wonka helps him into the mold and gets distracted. The mold closes, and the chocolate pours over his body and he is suffocating and nearly drowning in it. And it hardens around him, which feels terrible. He’s trapped. He’s alive but can’t be seen or heard. No one knows where he’s gone. Then he gets taken to Wonka’s house to be the chocolate boy in Wonka’s son’s Easter basket.

Charlie is waiting for the mold to be cracked open the next day, when the son will get his Easter treat. That’s when burglars come into the house to steal millions of dollars and jewelry. Charlie has witnessed this — there are tiny eyeholes in the chocolate — but they never realized the chocolate boy was alive. So he groans and alerts Wonka and his wife.

Totally a story suitable for mass consumption. I wonder why the editor convinced him to change his race, rofl.
